Description

Technical Field

[0001] This utility model relates to the field of steel structure connection technology, and in particular to a quick-assembly steel structure. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of components such as beams, steel columns, and steel trusses made of steel sections and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. The components or parts are usually connected by welds, bolts or rivets. Due to its light weight and simple construction, it is widely used in large factories, stadiums, and super high-rise buildings.

[0003] Existing steel structure assembly relies excessively on bolts or rivets for connection, resulting in cumbersome and inefficient procedures. Taking the assembly of a single steel section as an example, due to the length and weight of the steel section, the positioning process alone requires multiple people, and additional personnel are needed to tighten the bolts. The entire process is not only labor-intensive but also time-consuming. More importantly, bolted connections require extremely high precision in hole alignment. Even a slight deviation in the hole position necessitates repeated adjustments to the steel section's position, further extending assembly time and potentially causing wear and tear on components due to repeated adjustments, affecting the stability of the connection. In severe cases, this can even delay the overall construction schedule, causing numerous inconveniences to the project. Utility Model Content

[0004] The purpose of this utility model is to provide a quick-assembly steel structure to solve the problems mentioned above in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a quick-assembly steel structure, including a support platform, a first connecting steel plate, a second connecting steel plate, a first H-beam, and a second H-beam. The inner wall surfaces at both ends of the first H-beam and the second H-beam are provided with assembly devices. The assembly devices include protrusions fixedly installed on the inner wall surfaces at both ends of the first H-beam and the second H-beam. Grooves are provided on both the upper and lower sides of the first connecting steel plate and the second connecting steel plate. The size of the protrusions and the size of the grooves are matched.

[0006] Preferably, a partition is fixedly installed between the first connecting steel plate and the second connecting steel plate, and the first connecting steel plate and the second connecting steel plate form clearance grooves at their left and right ends with the help of the partition, and the size of the clearance grooves is adapted to the size of the vertical ends of the first H-beam and the second H-beam.

[0007] Preferably, the surfaces of the vertical ends of the first H-beam and the second H-beam are provided with a first through groove, the surface of one side of the first connecting steel plate is provided with two second through grooves, and the surface of one side of the second connecting steel plate is provided with two slots.

[0008] Preferably, the first through slot, the second through slot, and the slot are all the same size.

[0009] Preferably, a plug rod is movably inserted into the slot, the end of the plug rod away from the slot passes through the first through slot and the second through slot and extends out of the second through slot, and a pull ring is fixedly installed on the surface of the end of the plug rod away from the slot.

[0010] The effect achieved by the above components is that by utilizing the convex strips on the H-beam and the grooves on the connecting steel plate for sliding engagement, the pre-positioning of the H-beam and the connecting steel plate can be quickly achieved, eliminating the cumbersome hole alignment steps in traditional bolt connections and significantly shortening the assembly time.

[0011] Preferably, a reinforcing device is provided on one side surface of the first connecting steel plate. The reinforcing device includes two grooves formed on one side surface of the first connecting steel plate, and a sliding plate is slidably connected inside each of the two grooves.

[0012] Preferably, an extension plate is fixedly installed on the side of the skateboard, and bolts are threadedly connected to the surface of the extension plate. Two sets of threaded holes matching the bolts are opened on one side surface of the first connecting steel plate, and each set of threaded holes consists of two separate threaded holes.

[0013] Preferably, a plug rod is fixedly installed on the surface of the skateboard, and the outer wall surface of the plug rod has a plug hole that matches the plug rod.

[0014] The aforementioned components achieve the following effects: by using a sliding plate to drive the plug rod into the insertion hole of the plug rod, the radial rotation of the plug rod can be restricted. With the help of bolts, the sliding plate is fixed to the connecting steel plate, forming a double lock on the plug rod, preventing it from loosening under vibration, stress, or other conditions, and further improving the overall structural stability.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, by setting up an assembly device, the H-beam and the connecting steel plate can be quickly pre-positioned by sliding the convex strip on the H-beam with the groove on the connecting steel plate, eliminating the cumbersome hole alignment steps in traditional bolt connections and significantly shortening the assembly time. The design of the clearance groove allows the vertical end of the H-beam to be accurately embedded, further ensuring the accuracy of the connection. A single person can complete the initial assembly, reducing labor costs. At the same time, the plug rod passes through the through groove of the H-beam and the connecting steel plate and is inserted into the slot to form a through-type fixation, which can effectively limit the axial movement and shaking of the H-beam. Compared with traditional bolt connections, this structure has a more uniform stress distribution, reduces local stress concentration, and reduces safety hazards caused by component deformation during long-term use.

[0023] Example 1, as Figure 1-5 As shown, a quick-assembly steel structure includes a first connecting steel plate 1, a second connecting steel plate 4, a first H-beam 5, and a second H-beam 6. The flange width of the first H-beam 5 and the web thickness of the second H-beam 6 are 150mm and the material is Q355 steel.

[0024] Reference Figure 1-4As shown in this embodiment: Assembly devices 2 are provided on the inner wall surfaces of both the upper and lower ends of the first H-beam 5 and the second H-beam 6. The assembly devices 2 include protrusions 21 fixedly installed on the inner wall surfaces of both the upper and lower ends of the first H-beam 5 and the second H-beam 6. Grooves 22 are provided on both the upper and lower sides of the first connecting steel plate 1 and the second connecting steel plate 4. The size of the protrusions 21 matches the size of the grooves 22. A partition 23 is fixedly installed between the first connecting steel plate 1 and the second connecting steel plate 4. The partition 23 forms clearance grooves on the left and right ends of the first connecting steel plate 1 and the second connecting steel plate 4, and the size of the clearance grooves matches the size of the vertical ends of the first H-beam 5 and the second H-beam 6. First through grooves 24 are provided on the surface of the vertical ends of the first H-beam 5 and the second H-beam 6. Two second through grooves are provided on one side of the first connecting steel plate 1. The groove 25 has two slots 26 on one side surface of the second connecting steel plate 4. The dimensions of the first through groove 24, the second through groove 25 and the slot 26 are the same. A plug-in rod 27 is movably inserted into the slot 26. The end of the plug-in rod 27 away from the slot 26 passes through the first through groove 24 and the second through groove 25 and extends out of the second through groove 25. A pull ring 28 is fixedly installed on the surface of the end of the plug-in rod 27 away from the slot 26. The cross-section of the protrusion 21 is 10mm×10mm and the length is the same as the flange of the H-beam. The protrusion 21 slides with the groove 22 to achieve pre-positioning. The vertical ends of the first H-beam 5 and the second H-beam 6 are inserted into the clearance groove and then fit against the partition 23. The contact surface between the protrusion 21 and the groove 22 is coated with grease. All metal parts are hot-dip galvanized with a zinc layer thickness ≥85μm and a salt spray resistance test ≥1000 hours.

[0025] Reference Figure 3-5 As shown in this embodiment: a reinforcing device 3 is provided on one side surface of the first connecting steel plate 1. The reinforcing device 3 includes two grooves 31 opened on one side surface of the first connecting steel plate 1. A sliding plate 32 is slidably connected inside the two grooves 31. An extension plate 33 is fixedly installed on the side of the sliding plate 32. A bolt 34 is threadedly connected to the surface of the extension plate 33. Two sets of threaded holes 35 matching the bolts 34 are opened on one side surface of the first connecting steel plate 1. Each set of threaded holes 35 consists of two separate threaded holes 35. A plug rod 36 is fixedly installed on the surface of the sliding plate 32. A plug hole 37 matching the plug rod 36 is opened on the outer wall surface of the plug rod 27.

[0026] Working principle: When using this device, first check whether the installation positions of the first connecting steel plate 1 and the second connecting steel plate 4 are flat to ensure the stability of subsequent assembly. When assembling the first H-beam 5, align the protrusions 21 on the inner walls of the upper and lower ends of the first H-beam 5 with the grooves 22 on the upper and lower sides of the first connecting steel plate 1 and the second connecting steel plate 4, and slowly slide along the grooves 22. The contact surfaces of the protrusions 21 and the grooves 22 are coated with grease to reduce friction, so that the vertical end of the first H-beam 5 gradually enters the clearance groove on the left end until one side surface of the vertical end is tightly attached to the partition plate 23, completing the initial positioning. Following the installation steps of the first H-beam 5, align the protrusions 21 on the second H-beam 6 with the grooves 22 on the inner walls of the first H-beam 5. 1. Align the first H-beam 5 with the corresponding groove 22 and slide it so that its vertical end also enters the clearance groove and fits against the partition 23. At this time, the first H-beam 5 and the second H-beam 6 are initially connected to the first connecting steel plate 1 and the second connecting steel plate 4. When fixing the first H-beam 5 and the second H-beam 6, take the plug-in rod 27, hold the pull ring 28 and pass one end of it through the second through groove 25 of the first connecting steel plate 1, the first through groove 24 of the vertical end of the first H-beam 5, and finally insert it into the slot 26 of the second connecting steel plate 4. Ensure that the plug-in rod 27 extends into the second through groove 25 to a moderate length. Install another plug-in rod 27 in the same way. The first H-beam 5 is connected by the two plug-in rods 27. The second H-beam 6 is completely confined on the first connecting steel plate 1 and the second connecting steel plate 4 to prevent it from sliding along the groove 22. To further strengthen the connection, slide the sliding plate 32 on one side of the first connecting steel plate 1, so that the sliding plate 32 moves along the groove 31 towards the insertion rod 27, driving the insertion rod 36 on the surface of the sliding plate 32 to move synchronously until the insertion rod 36 is precisely inserted into the insertion hole 37 on the outer wall of the insertion rod 27, restricting the radial rotation of the insertion rod 27. When the insertion rod 36 is fully engaged with the insertion hole 37, tighten the bolt 34 on the surface of the extension plate 33, screw it into the threaded hole 35 at the corresponding position of the first connecting steel plate 1, and tighten it. Lock the position of the sliding plate 32 with the bolt 34, so that the insertion rod... 36 remains within the insertion hole 37, thus firmly fixing the insertion rod 27 in the slot 26. During disassembly, first loosen the bolt 34 in the reverse direction to disengage the bolt 34 from the threaded hole 35. Then slide the sliding plate 32 to allow the insertion rod 36 to exit the insertion hole 37. Hold the pull ring 28 to pull the insertion rod 27 out of the slot 26 and through groove. Finally, slide the H-beam along the groove 22 in the reverse direction to separate the first H-beam 5 and the second H-beam 6 from the connecting steel plate. Through the above process, by utilizing the pre-positioning of the protrusion 21 and the groove 22, the through fixation of the insertion rod 27, and the secondary locking of the reinforcement device 3, the rapid assembly and stable connection of the steel structure are achieved, while also taking into account the convenience of disassembly.
